With the combo of Quick-Step and Focused Zeal, it adds a dimension of a hit-and-run micro that can be possible and favorable. The Psi Storm and SC1 Hallucination helps HighZealot further in general.

It is also of note that Blink (and any variant thus Quick-Step) makes 100% direct missiles fail to hit the target so with enough micro and prediction, you can potentially avoid a lot of ranged attacks. Also useful to just blink out of Psi Storm attack or an upcoming Yamato Gun shot and so on.
